"In fact, the statistician on the panel, Peter Bloomfield, a member of the Royal Statistical Society, came to the opposite conclusion of Prof Hand."

Mann has been repeating this arrogant duplicitous spin continuously since Climategate and refuses to acknowledge any problems whatsoever with his infamous doomsday hockey stick graph.
